General Description

Centrimide Nalidixic Agar Kit contains
ReadyPlate^™CN Agar plates of 55mm diameter is a selective and differential chromogenic culture medium. It is a standard medium in water testing for simultaneous isolation and enumeration ofPseudomonas aeruginosafrom water samples. Gelatine peptone and Casein hydrolysate supply amino acids and other complex nitrogenous substances. In the presence of Cetrimide (a selective agent that acts as a quaternary ammonium cationic detergent), the growth of bacterial cells other thanP. aeruginosais inhibited due to the release of nitrogen and phosphorous. Nalidixic acid present in the supplement also improves the inhibition of the accompanying microbial flora. The amount of potassium sulphate and magnesium chloride enhances the pigment production ofPseudomonas aeruginosa.
EZ-Pak Filters are ready-to-use, sterile filters made of Mixed cellulose esters (MCE) with 0.45 μm pore size, white, gridded and 50mm diameter. These filters possess high recoveries.
